taking a podcast and making audio available to asterisk

(see also: Phone2Podcast)

We use the Blasterisk Indymedia service for taking calls from PSTN...

the below script is called by crontab on the blasterisk server. the podcast feed address is on indypgh.org (Pittsburgh Indymedia)

we have a weekly radio show and a podcast feed for that show. this script checks the podcast feed, and if it finds a new show, it downloads the show, converts/resamples the file, and then puts it in a specific location.

# mtoups 2006/07/30

# get the xml file, find newest show
audiofileurl=`curl -A "blasterisk podcast parser booyeah" -s -L http://indypgh.org/syn/rustbelt-podcast.xml | tr '\r' '\n' | tr \' \" | sed 's/>/>\n/g' | sed -n 's/.*url="\([^"]*\)".*/\1/p' | sed 's/&/&/g' | head -1`

filename=`echo "$audiofileurl" | awk -F / '{print $NF}' | sed -e "s/%20/ /g" -e "s/%27/'/g" -e "s/%23/#/g" | awk '-F?' '{print $1}'`

#if we already downloaded this show, we're done, exit
test -f /tmp/$filename && exit 0

#otherwise, download
curl -A "blasterisk podcast parser" -o /tmp/$filename -L $audiofileurl

#convert to gsm
sox /tmp/$filename -r 8000 -c 1 /var/lib/asterisk/sounds/blast/rustbelt-latest.gsm resample -ql
#could also be a pcm wav, but needs to be 8khz resampled either way

then, the following lines are in the context menu for the Pittsburgh IMC phone number. the menu also

#to listen to this week's rustbelt radio, press 4
exten => didx-pitts,n,Background(blast/to-listen-to-rustbelt)
exten => didx-pitts,n,Background(blast/press-4)
exten => didx-pitts,n,Background(silence/1)

#play the latest show
exten => 4,1,Background(blast/rustbelt-latest)

other ideas include, sending the podcast to people's voicemail, calling somewhere and playing it, etc. please share if you're doing this!
